A little bit of both. I want and need to use the car as a daily driver but would like to at least flow the head and have the pistons, conrods, etc balanced. Looking to retain the original cam if still in good condition as well as the existing single throttle body system. It already has a branch and freeflow so would like to keep the fuel economy fair but with a little extra power. Strong but reliable

The engine is already out of the car and has been stripped down. Who can you guys recommend or who is willing to do the job?

Erm...........I did. :whistle: I took my time but got the complete engine and gearbox out and then dismantled the whole engine with exception to the crank (Still in block).

The crazy thing is so far I've been getting pricing ranging from R9000 to R15000 to rebuild the engine. 8O

Well then do it yourself. If you took it apart, surely you should be able to put it all together again.

We can get you the torque specs for all the bolts on this motor. :duim:

Just take it to a engineering place to replace your valve stem seals in your head and they should be able to port and flow the head for you as well. What area do you live in?

I would like to try but I've never rebuilt an engine. Dismantling is easy but I'm just worried I c#ck up the fitting. I'm from Gordons Bay but the engine is in Somerset West. If you guys can help with the torque figures for the bolts, it would be awesome.

I've gotten pricing from one guy for a X20EXV for R8000. Do you guys know if it would use the same Computer, loom, clutch and flywheel that I currently have? Are the engine mounts the same as the 20SEH? Might work out cheaper to fit new motor and sell the 20SEH off in parts.

No ways man. That's not even funny. Only buy a new motor if you want to upgrade. What was wrong with the SEH in the first place? I have a SEH too and it's really simple. I just moved out of Strand but I can guide you through it and we can make it into a DIY or something. The parts inly fit in one way, the only thing you must be really careful about is the bearing caps must be exact and the pistons must be in the right way too.

Thanks EvanTate...

Really appreciate the offer. The engine had "blow-by" and was using 3 liters of oil a month. Car was jerking badly and could feel the engine was close to throwing in the towl.

Took the motor to mechanic for check. Needs full rebuild. New pistons, rings, mains, bearings, belts, rebore, head recon, crank work, oil pump, water pump and everything else inbetween. But he recommended a rebuild as well.

I spoke to him about the X20XEV and said that it's not exactly a straight swop anyway. Would need new computer, wiring loom and then some of the existing piping around engine would need to be re-routed to fit the new motor. Just a lot of extra hassle.

So short end of the story, will be rebuilding motor. Will send motor to Motor Masters for engineering and fitment of all new parts and assembly of complete engine. Head to Headzone for full recon, re-seating, new valve stem seals and gasflow.

Can anyone give me the details of the guy in Eerste River (I think) who does balancing?

Hi there,

No. My 20SEH was in Opel Astra Euro with standard style clocks but surely they are the same motor. Can anyone else comment?

Is the C20SEH and the 20SEH the same engine?
